Part of a series on the COVID-19 pandemic Scientifically accurate atomic model of the external structure of SARS-CoV-2. Each "ball" is an atom. COVID-19 (disease) SARS-CoV-2 (virus) Cases Deaths ...
In February 2020, the World Health Organization (WHO) said it did not expect a vaccine against SARS‑CoV‑2 to become available in less than 18 months. [9] Virologist Paul Offit commented that, in hindsight, the development of a safe and effective vaccine within 11 months was a remarkable feat. [10]
The Janssen COVID‑19 vaccine is used to provide protection against infection by the SARS-CoV-2 virus in order to prevent COVID‑19 in people aged eighteen years and older. [36] [1] The vaccine is given by intramuscular injection into the deltoid muscle. The initial course consists of a single dose. [43]
The vaccine consists of a version of the receptor binding domain (RBD) of the SARS‑CoV‑2 spike protein, together with the adjuvants aluminium hydroxide gel and CpG 1018. [2] As the RBD protein is poorly immunogenic alone, adjuvantation is essential for a RBD-based vaccine immunogenicity. [9]
